On the Secrecy Capacity of MIMO Wiretap Channels: Convex Reformulation and Efficient Numerical Methods
Anshu Mukherjee, Björn Ottersten, Le-Nam Tran
This paper presents novel numerical approaches to finding the secrecy capacity of the multiple-input multiple-output (MIMO) wiretap channel subject to multiple linear transmit cova…
Widely-distributed Radar Imaging Based on Consensus ADMM
Ruizhi Hu, Bhavani Shankar Mysore Rama Rao, Ahmed Murtada +2
A widely-distributed radar system is a promising architecture to enhance radar imaging performance. However, most existing algorithms rely on isotropic scattering assumption, which…
Multi-Antenna Data-Driven Eavesdropping Attacks and Symbol-Level Precoding Countermeasures
Abderrahmane Mayouche, Wallace A. Martins, Christos G. Tsinos +2
In this work, we consider secure communications in wireless multi-user (MU) multiple-input single-output (MISO) systems with channel coding in the presence of a multi-antenna eaves…
Transfer Learning and Meta Learning Based Fast Downlink Beamforming Adaptation
Yi Yuan, Gan Zheng, Kai-Kit Wong +2
This paper studies fast adaptive beamforming optimization for the signal-to-interference-plus-noise ratio balancing problem in a multiuser multiple-input single-output downlink sys…
Radio Resource Management Techniques for Multibeam Satellite Systems
Steven Kisseleff, Eva Lagunas, Tedros Salih Abdu +2
Next-generation of satellite communication (SatCom) networks are expected to support extremely high data rates for a seamless integration into future large satellite-terrestrial ne…
Coverage Probability and Ergodic Capacity of Intelligent Reflecting Surface-Enhanced Communication Systems
Trinh Van Chien, Lam Thanh Tu, Symeon Chatzinotas +1
This paper studies the performance of a single-input single-output (SISO) system enhanced by the assistance of an intelligent reflecting surface (IRS), which is equipped with a fin…
